Biogas in Dhanawas

Dhanawas village is about 50 km Southwest of Delhi.  The village 
situated in the Farrukhnagar block, is about 15 km from the 
district headquarters Gurgaon, in the State of Haryana.  There 
are about 181 households with a total population of 1056.  Tata 
Energy Research Institute (TERI) has been working in the village 
since 1984 and a number of technology interventions including 
biogas, improved chulhas, solar lanterns, solar street lights, 
biomass gasifier, biomass briquettes, etc.  have been attempted. 
Among all the interventions made in the village, biogas plant 
has emerged as a most successful and infact, a competing 
technology to LPG (growth of biogas plant was twice than that of 
LPG during the last decade). 
 
 
Time saving is the factor which scored highest and from the 
feedback it was found that, the time saved by the use of biogas 
for cooking, was spent in attending to other domestic chores or 
in relaxation. 
 
The second ranking of institutional issues 
reflected the confidence the people had with the implementing 
agency.  This confidence may be due to their observation of the 
implementing agency on other activities or functionality of 
installed biogas plants.  
 
Smoke removal was perceived as one 
important benefit ranked third which besides resulting in 
improved health, reduced the cleaning of walls and whitewashing 
them.  
 
Since, the biogas meet some large parts of the cooking in 
the households, use of biomass fuels including dung cake has 
reduced, though, not eliminated completely.  Thus, it has become 
possible to divert a large proportion of dung as fertilizer in 
the fields.  This alternate use of dung as fertilizer ranked 
fourth among the factors. 
 
The fifth ranking factor was a group 
of other reasons where convenience of operation of biogas plants 
over types of stoves and less or no maintenance problem along 
with its relatively safer operation was acknowledged by the 
users. 
 
Fuel saving that the researchers, policy makers, and 
implementing agencies have paid maximum attention, did not score 
well and ranked sixth according to the users.
 
The biogas light generally used as a standby in case of power failure is another perceived benefit by the villagers and as ranked seventh.  
 
The subsidy involved, by the government (33%) and an additional 
subsidy by TERI (another 33%) was identified as eighth important 
factor, showing that it was not a limiting criterion.  Less 
effort in cleaning the vessels and kitchen and the plant as a 
status symbol scored last in the ranking of factors.
